Hi,

This series fixes a number of issues found while reviewing the opt4001
driver. All of them date back to the initial submission of the driver
in commit 9a9608418292 ("iio: light: Add support for TI OPT4001 light
sensor"). I have not added Fixes: tags; happy to resend with them if
preferred.

Patch 1 fixes a read-modify-write in opt4001_power_down() that reads
the device ID register instead of the control register, corrupting the
CTRL configuration on the way to power down.

Patch 2 fixes an incompatible pointer type passed as the remainder
argument to div_u64_rem(), which takes a u32 * rather than an int *.

Patch 3 makes opt4001_write_raw() reject integration time writes with
a non-zero integer (seconds) part, which were previously accepted
silently based on the microseconds part alone.

Patch 4 fixes reversed GENMASK() arguments in the (currently unused)
fault count mask definition and adds the _MASK suffix for consistency
with the neighbouring defines.

Thanks,
